VALERIUS D. ANDERSON, OF CLEVELAND, OHIO.

PRESS.

SPECIFICATION forming part of Letters Patent No. 474,802, dated May 17, 1892.

Application filed November 28,1891. Serial No. 113,428. (No model.)

To all whom it may concern:

' Be it known that I, VALERIUS D. ANDER- SON, a citizen of the United States, residing at Cleveland, in thecounty of Ouyahoga and State of Ohio, have invented certain new and usefullmprovements in Presses, of which the following is a specification.

My invention relates to presses; and it consists in various features, details, and combinations hereinafter set forth and claimed.

In the drawings,Figure 1 is a face view of my improved machine; Fig. 2, a top plan view; Fig. 3, a side View, partly in'section and on a larger scale, of the drum or cylinder and the pressure-rollers; and Figs. 4 and 5, views illustrating the construction ofthe lagchain.

A indicates a drum or cylinder, preferably flanged, mounted upon a shaft B, which latter is journaled in the main frame of the machine. This main frame comprises two semicircular plates O, suitably connected to each other and having a series of radial slots or Lopenings D, which have on their side walls guiding ribs or flanges 0,, as shown'inFig. 1,

and mounted in these openings and guided in their movements by the ribs are suitablyforined blocks or cross-heads E, which carry the pressure-rollers F. The desired pressure is secured by means of powerful springs G, (exerting a pressure of several tons), which bear atone end against plates or caps b at the outer ends of the slots and at their inner ends against similar plates or caps 0, carried by large and heavy screws H, which latter are supported at their inner ends by the crossheads E, into which they screw. Of course, by turning the screws the action of the spring may be varied and a greater or less degree of pressure applied to the material passing between the rollers and the drum, or, more properly speaking, to the material between the drum and the lag-chain I, which runs in contact with the rollers.

In lieu of the springs and screwaweighted lever G and rod H may be employed, as also represented in Fig. 1.

The side plates 0 are provided with a lateral flange d, Figs. 1 and 3, through which passes a series of adjustable stops e, which for convenience may be made in the form of screws passing through threaded holes in the right bars K,-as shown in Fig. 1. K are each formed with an enlarged portion flange and bearing at their outer ends against the inner or under face of the cross-heads, these stops serving to limit the approach of certain of the rollers toward the drum, for a purpose presently explained.

Projecting from main portion of the frame in which the drum is journaled are four arms J, arranged in pairs and connected by the up- These bars at or about the center, in which is formed an pivoted at a point between its ends to an arm Z, projecting from the connecting-bar K, while to the upper end of the lever there is attached a cord or connection m,which passes over a sheave or pulley Nat the upper end of a pair of uprights secured to the main frame. A weight n at the end of the connection m tends to urge the frame L away from the drum or cylinder A.

The lag-chain I comprises a series of lags 0, curved on their inner and outer faces, as shown in Figs. 1, 3, and 5, to conform to the curvature of the drum or cylinder. Each of the lags is provided at one end with a central tongue 19 to enter between corresponding arms g at the opposite end, the arms and the tongue being each perforated to receive a connecting pin or rivet T. It will be noticed upon reference to Figs. 1, 8, and 5 that the arms and tongue are slightly undercut and that the pivot connecting the lags is placed comparatively near the inner face of the chain, so that there shall be no projections of any kind upon the outer face to interfere with the smooth and proper action of the pressurerollers thereon. lags (shown in Fig. 4:) will be closed up as the chain passes from the drum onto the frame L, the chain sagging slightly and thereby bringing the squared ends of the lags against each other and rendering the chain self-supporting The opening between the r in a degree. The material is fed onto the upper face of the lower portion of the chain close to the drum, and in order to insure the proper entrance of the material into the space between the drum and chain I so adjust the screws or stops e as to preclude the rollers from pressing hard upon the chain until the materialhas well entered. It willbe seen upon reference to Fig. 3 that the five lower rollers are so adjusted relatively to the drum or the lag-chain by means of these stops or screws that there is no pressure of any consequence exerted until the material reaches the upgoing side of the drum or a point at about opposite the fifth roller from the bottom. The lowermost roller is set farther away from the drum than any of the others and the succeedin g rollers are set gradually closer to the drum, so that the space between the drum and the chain shall assume the form of a wedge, thereby forming a tapering channel, into which the material may be gradually fed without any tendency to choke up. This is specially important in pressing garbage and like materials containing large quantities of foreign matters, which require a large feed-opening.

In lieu of this, however, the same effect may bage, oleo, and similar slippery greasy matters.

The devices for supplying and removing the material may be arranged as shown in my patent, No. 464,600, dated December 8, 1891, and form no part of the present invention. So, too, the drum or cylinder may be heated, as in my prior patent above referred to, if desired.

Having thus described my invention, what I claim is 1. In a press, the combination, with a drum or cylinder, of a lag-chain passing therearound and adapted to hold the underlying material against the outer face of the drum, and a series of rollers bearing against the back of the lag-chain throughoutits contact with the drum and adjustable toward and from the drum, and a yielding-pressure mechanism for the rollers.

2. In a press, the combination, with a main frame, of a drum A,journaled therein, a lagchain I, passing therearound and adapted to hold the underlying material against the outer face of the drum, a series of pressure-rollers F, journaled in sliding bearings E and adapted to bear upon the chain, adjusting mechanism substantially such as shown for the rollers, whereby they are set away from the chain at the upgoing side of the drum to form a gradually-contracted throat or feed-opening, and a yielding-pressure mechanism for the rollers.

3. In a press, the combination, with a drum or cylinder and't-he lag-chain passing therearound, of the frame 0, having the radial openings D, the cross-heads and rollers mounted therein, the adjustable stops 6 for limiting the inward movement of the rollers and crossheads, and means tending to urge the latter inward.

4. In a press, the combination, with a main frame, of a drum A, journaled therein, a semicircular non-rotating supporting-frame L of approximately the same diameter as the drum, alag-chain passing about the drum and frame, and a weighted lever connected with the frame and tending to urge it away from the drum, and thereby keep the chain taut, all substantially as shown and described.

5. In combination with a main frame and the drum mounted therein, arms J, projecting from the main frame, bars K, connecting the arms and provided with arms Z and ways f, frame L, provided with blocks g, supported in the ways, a weighted lever M, pivoted to arm I and connected with the frame by rod 70, and a lag-chain passing about frame L and the drum.

6. In a press, the combination, with a main frame having the separated plates 0, provided with radial openings D, of boxes or bearings E, mounted within the openings, rollers F, journaled in the boxes, stops or screws e at the inner ends of the openings, screws H and springs G at their outer ends, a drum, and a lag-chain passing between the drum and rollers, all substantially as shown and described.

In witness whereof I hereunto set my hand in the presence of two witnesses.
